UMIG Polycarbonate Greenhouse Panels 6-Pack 70.9 x 23.6 in (6 mm) Clear Twin-Wall, UV-Coated for Less Seams

These UMIG greenhouse panels are twin-wall polycarbonate sheets (70.9" × 23.6" × 0.24" / 1800 × 600 × 6 mm) sold in a 6-piece pack intended for small- to medium-sized greenhouses, pergolas, and covered corridors. Each sheet features double-sided UV protection to limit yellowing and cracking, and a translucent finish that transmits roughly 80% of light while maintaining privacy from a distance. The panels are lighter and more impact-resistant than glass, and their length reduces seams for fewer leak points and faster installation on arched or straight frames.

How do these panels perform in sun, rain, and cold?

The twin-wall construction plus double-sided UV coating preserves clarity and strength under prolonged sun exposure while repelling water and resisting impact. They moderate interior temperatures, allowing more light in during winter and reducing overheating in summer compared with single-wall plastics.

• Double-sided UV coating prevents early yellowing and cracking.
• High-impact polycarbonate resists hail and accidental knocks.
• Twin-wall air gap adds insulation to reduce heat loss.
• Long 6' sheets mean fewer seams and reduced leak risk.

What size coverage and framing works best with these sheets?

Each panel measures 70.9" × 23.6" and is 0.24" (6 mm) thick, making a single sheet suitable for covering most 6 ft frame bays with minimal joints. They bend for gentle curves and fit arched or pitched greenhouse roofs when supported correctly.

• Sheet size: 70.9" × 23.6" (1800 × 600 mm) — six pieces per pack.
• Thickness: 0.24" (6 mm) twin-wall for strength and insulation.
• Works on straight, arched, and gently curved frames with proper screws and caps.
• Fewer seams per bay lower installation time and leak points.

How much light do these panels let through and how clear are they?

The panels deliver about 80% light transmission, providing bright, diffuse daylight ideal for plant growth without harsh glare. Their translucent finish maintains visual clarity nearby while softening detail at a distance, offering both visibility and discretion.

• Approximately 80% light transmission for balanced photosynthesis support.
• Translucent surface preserves clear plant views up close.
• Diffused light reduces hotspots and uneven sun exposure.
• UV coating helps keep clarity over years of sunlight exposure.

What installation and maintenance should I expect?

Installation is straightforward thanks to the uniform double-sided coating and manageable weight. Use compatible profiled screws, rubber washers, and end caps; apply sealants where required and avoid overtightening to prevent panel stress. Maintenance is minimal — periodic cleaning and inspection for debris and seal integrity are usually sufficient.

• Install with capped screws and rubber washers to prevent leaks.
• Do not overtighten fasteners; expandability is normal with temperature changes.
• Clean with mild soap and soft cloth to avoid scratches.
• Inspect seals and overlap areas after severe weather.

Who is this product for? These UMIG polycarbonate panels are designed for home gardeners, hobbyists, small commercial growers, and DIYers building or upgrading medium-sized greenhouses, pergolas, covered walkways, chicken coops, and nursery structures. Choose this 6-pack if you want durable, UV-protected, and easy-to-install roofing sheets that reduce seams, improve insulation versus single-wall plastic, and keep plants visible without direct glare. They suit projects where impact resistance, long-term clarity, and lower maintenance are priorities rather than ultra-high insulation or soundproofing found in thicker multi-wall systems.
